furnaces, and has for an object to provide a crematoryfor effectually burninggarbage and similar waste matter..

The invention contem lates amon other features, the provlslon of a crematory so constructed and arranged that garbage placed therein will be entirely incinerated and will, particularly when the garbage is wet or moist, be gradually dried, charred and then consumed by the intense heat produced in the body of the furnace. 1

Still further einbodments of the invention reside in a garbage Crematory in which provision is made to effectually consu'me'the gases which are formed and pass oif during the process OflIlClIlGIfttlOD. of the arbage,

these gases being received in a compartment 7 adjacent the usual stack or outlet flue and in which compartment the gases, sub ected to an intense heat, will result in the combustion of the matter contained in the gases so as to reduce obnoXiousodors which ordinarily would pass out through the stack.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which: 7 V

Figure 1 is a vertical longitudinal sectional view taken through the furnace on the line 11 in Fig. 2; Fig. 2 is a horizontal sectional view of the furnace, taken on the line 2-2 in Fig. 1; Fig. 3 is a vertical transverse sectional view taken on the dime 33 in Fig. 1; Fig. 4 is a vertical sectional view taken on the line 4-4: in Fig. 1; and Fig. 5 is a vertical sectional View taken on the line 55 in Fig. 2, looking in the direction of the arrow.

Referring more particularly to the views, 10 represents the base, the front wall being indicated by the numeral 11 and the'rear wall by the numeral 12, said front and rear 7 walls 11 and 12 and the bottom or base 10, together with side walls 13 and 14 and an arched roof 15, forming a casing 16 into which the garbage is to be dumped through a substantially circular hopper 17 formed 1 i i in the roofof the ca'singxThe walls form mg the casing are built of brick and the casing is suitably lined with a firebrick or other refractory material, suitable buckstays or other reinforcing rods" 18 being provided to passthrough the side and end walls and-also through the roof in order to substantially reinforce the entire structure.

It will be noted that although the exterior of the casingis of substantially a rectangular construction, the inner wall of the easing is not defined by the usual corners but at its rear is'curv'ed as shown. The front wall 11' is preferably covered with'a cast iron 'or other suitable shell 19 which, if desired, may also cover the entire structure. A flue 20 isformed in the side wall 1 1 to connect with a passage 21- sufficiently large to be termeda compartment, said compartment being formed by a continuation of'the front wall'll and walls 22. The compartment '21 terminates in a stack 22 upstanding at one end of the compartment. Asuitable opening 23 in the front wall 11 communicates with a firebox 24 formed in the casing 16, saidfirebox being provided with a grate 25 and a hopper 26 arranged to supply r1181 to the gratefl25. An upstanding wall substantially triangular in cross. section and indicated bythe numeral '27 forms the fire-' box with the side wall 13, with the face of thewall forming the firebox extending substantially at right angles to the frontof the furnace, the other face of the upstanding wall 27 beinginclined as shown, with a grate-like platform 28 arranged in this portion of the casing and adjacent to the inclined face of the upstanding wall 27 and which therefore substantially separates the providedso that the consumed matter or i ashes can be removed from the casing,

The compartment 21 has a right angled extension forming a firebox 3O communica ting with the exterior by an opening 31 for the removal of ashes andthe like, a grate 32 being arranged-in the firebox 30, with a hopper 33 communicating with the firebox to supply fuel-to the grate. A wall .in the nature of a bridge'wall 34 is arranged to extend transversely G0 the portion of the compartment 21 extendingat right angles therer to and which formsrthe firebox as mentioned,

and it will be clearlyseen that the firebox 30, together with its. grate 32 and hopper 33, aifords a conveniently'arranged means for a fire producingan intense heat which will result in tli: production of an intense temperature in the compartment 21. A second flue 31 is formed in the side wall '14; for the purpose of establishing direct communication of the fire chamber 30 with the grate 28.

The casing 16 is in the nature of a storage chamber and a suitable closure 35 having been removed to uncover the hopperl'? the garbage that is to be incinerated is dumped intothe hopper andwill be received in the storage chamber. A fire having been produced upon the grate 25 with the. fuel fed to thefire through the hopper 26, an intenseheat will result in the casing or storage chamber, thus charring the garbage and gradually evaporating the moisture therefrom until the garbage reaches a point where .it will be substantially"consumed, the heat in the storagechamber impregnating. the

garbage and reaching every particle thereof to effect as near a perfect combustion of the garbage as can beobtained. As the garbage is consumed it is raked on to the platform 28 and which, as mentioned, 18 somewhat in the nature'of a large grate with the consumed or ash part of the garbage adapted to filter. through the grate and be removed through the ash removal ':opening 29 mentioned 1 heretofore. Now the gases, vwhich neces- SflIllYLWlll be-produced when the. garbage is consumed, passing from the storage chamher, will pass through the flue-2O into the compartmentx21 and in view of the fact that this compartment is subjected to any intense heat from the fire upon the grate 32,. it will be clearly apparent that the foreign particles willpass intothe compartment 21 and the obnoxious gases will be almost entirely consumed by the intense heat of the compartment so that the residue which passes up throu h the stack 22' will be substantially devoid of obnoxious odors. Thus it will be seen that the stack 22 providing a sufii cient draft for the heat produced inthe storage chamber to circlearound and penetrate the garbage will result in the-consumation and incineration. of the garbagein the manner mentioned, the curvature of the walls of the storage chamber and the arching of the roof. however, being important factors in guiding the heat currentsso that they will effectuall impregnate the garbage in the storage chamber and result in its effective incinerationin the manner mentioned.

With the construction set forth it will. be

clearly apparent that the stack 22' will be.

clear that the incineratingfurnace described .Wlll have its casing? or storagechamber and substantially smokeless finfview of the con sumption of the gases as they pass from the J storage chamber into the gas consuming;

compartment 21'and byhaving the gases pass out of the storage chamber and into the compartment 21they will :nothinder the proper:.incineration of the garbage in the compartment and will aid in rendering the incineration: more effective in that they will not clog the chamber to prevent the proper draft and the propercirculation of the heat currents produced in the firebox 24 and upon the grate 25 thereofa, Therefore, in the eon-a struction of the'apparatus shownjit will be 1 also its gas consuming compartment @heated; to a maximum temperature to incineratethe garbage and 'evaporatejany moisture: con-L I tained therein and; also consume the; gaseswhich are produced during the incinerating ter being efiectuallyconsumed to the extent that the stack provided as an outlet for :the

entirestructure will be substantially smoke-- less andidevoid of gases. and odors that would ordinarily'escape through the stack if.

operation, this latter mentioned w stemat-g they were notsubjected to. an intense heat. 7

for the purposeof consumingthe same.

The side wall 13 is. formed with a bulged li' portion36 providing an auxiliary chamber 37 forming a firebox which has communication with the casmg16 "by means of a pas-1.

It will be-fu'rther noted by'reference particularly toFig-Q that the provision-of the auxiliary chamber-and its fireboxes presents a structure in which the necessary heati requiredito incinerate the garbage can be governed. with respect to the amount of gal bage to be incineratedat onetime in the furnace, and to this end, if the incinerator; is not working at its full capacity and is not filled with garbage to its fullest extent, the operator can, if he desires, use=only one of the 'fireboxes and place-it in operation to produce the desired number of heat sunits r.

necessary to incinerate the: garbage con' tainedin the stora e chamber. On .the other hand. if the storage chamber is loaded to. its full capacity the mainzfirebox and auxiliary;- firebox can be set .inoperationand the fires.

produced therein will generate suflicient heat to incinerate the full amount of garbage contained in the storage chamber.
